RALPH M. MYERS. OF MUIR. MICHIGAN.

MEDICINE-DROPPIER.

To all whom it may concern:

Be it known that I, RALPH M. MYERS, a citizen of the United States,residing at Muir, in the county of Ionia and State of Michigan, haveinvented new and useful In'iprovements in Medicine -'Droppers, of whichthe following is a specification.

This invention relates to improvements in medicine droppers ordispensers and more particularly to a medicine dropper which isadapted'to beused in connection with the dispensing of liquids such aschloroform, ether, etc., which evaporate quickly when exposed to theatmosphere from bottles or like containers.

An object of this invention is the provision of a stopper for containersof this nature with which the amount of liquid dispensed from thecontainer can be regulated as well as the flow of the liquid, the latterbeing regulatable from drops to a steady stream as necessary or desired.

Another object of this invention is the provision of a device of thisnature so constructed that when the liquid notbeing dispensed from thecontainer the accidental admission of air thereinto is practicallyimpossible.

A still further object of this invention is the provision of adevice ofthis nature which is as simple in construction as is consistent with itsfunctionary operation and in the construction; of which is embodieddurability, efiiciency of operation and sim-- plicity of operation. I

WVith the foregoing and other objects in view, this invention consistsin such details of construction, combination and arrangement of parts aswill be hereinafter more fully described, illustrated in the accompanymgdrawings and claimed.

In describing the invention in detail, ref

erence will be had to the accompanying drawings wherein like charactersof reference designate like or corresponding parts ,throughout theseveral views, and in Specification of Letters Patent.

having a neck 2. It to be understood that in practical use any type ofcontainer that will fulfil the necessary requisites may be used.Inserted into the opening of the neck erably made of glass ortransparent material.

but it is to be understood that any suitable material may be employed intheir construction. The tube 5which will be hereinafter N referred to asthe dispensing tube" is of the same diameter its entire length andtermi-.

nates at the bottom of the stopper 3 as. is shown in Fig. 2 of thedrawings. The tube 6 which we will call the air tubev or vent is muchlonger than the tube 5 and extends downwardly into the bottom of themain; body portion of the container l andltapers slightly toward itslower end. Mounted in fluid tight engagement in the upper ends of thetubes 5 and 6 are two stoppers 7 and 8, respectively. The upper ends ofthese.

stoppers 7 and 8 are provided with caps 9 and 10 which have theprojections 11 and 12 extending upwardly therefrom. These-projections 11and 12 are each provided with an opening therethrough. Mounted in thestopper 3 is a member 14: which forms a pivoting point for the lever 15.The lever 15 has a handle portion 16 bent substantially at right anglesto the body or leverage portion 17 and extending preferably parallelwith the vertical lines of the container. The lever 15 is pivotallymounted upon the member 14 at 18 and has a rod 19 extending transverselythrough its end 20. This rod 19 extends through and is rigidly mountedin the openings in the projections 11 and. 12 of the caps 9 and 10 andforms a means whereby when the handle 16 of the lever 15 is operated thestoppers. 7 and 8 will be raised or lowered, according to the action ofthe lever 15, in or out of the tubes 5 and 6.

A coil spring 21 is connected to the leverage end 17 of the lever 15 at22 and to the. stopper 3 at 23. This coil spring keeps the leverageportion 17 of the lever 15 normally in a downward position thusfirmly'holding the stoppers 7 and 8 in the ends of the tubes 5 and 6whereby the device is normally closed and the admission of air into thecontainer and the contents thereof is prevented. By connecting thespring 22 to the lever 15, intermediate the pivotal point 18 and thestoppers 10 and 11, the stoppers will be more efliciently retained inthe tubes 5 and 6 because the retaining force of the spring will beadministered to the stoppers so as to eliminate the retarding action ofthe pivotal point which would be occasioned if the spring wereconnected, to the lever at a greater distance from the supports than thepivotal point of the lever.

When it is desired to dispense the liquid contained in the container 1therefrom the handle 16 of the lever 15 is pressed inwardly or in thedirection of the arrow 25 shown in Fig. 1 of the drawings, thus thestoppers 7 and 8 are forced upwardly and out of the ends of the tubes5and 6 and when the container is tipped the liquid contained thereinwill freely flow out of the tube 5. I The necessary air,is-admitted'into the bottle through the tube 6. The amount of liquid andthe flow thereof from the con-. tainer can be easily regulated by thepressing inward of the handle 16, for it will be seen from the foregoingdescription and the drawings that the more pressure exerted upon thehandle 16 and the farther inward:

it is bent the farther the stoppers 7 and 8 willbe drawn out of thetubes 5 and 6.

In practical fields, certain minor features of construction, combinationand arrangement of parts may necessitate alterations to which thepatentee is entitled, provided such alterations are comprehended withinthescope of what is claimed.

. What is claimed is:

1. A dropping attachment for liquid containers consisting of two tubularmembers mounted in a stopper for the mouth of said container, one ofsaid tubular members terminating at the inner end of said stopper, theother of said tubular members extending downwardly into the main bodyportion of the container said tubular members forming means for thedispensing of the liquid contained in the container stoppers mounted inthe outer ends of said tubular members, a member mounted in said stoppera lever pivotally mounted upon said last named member and connected tosaid stoppers, said pivoted lever forming means for automaticallyoperating said stoppers a handle upon said lever for facilitating theactuation ofthe same, a coil spring interposed between the leverage endof said lever and. said stoppers and connected to each of them, saidcoil spring forming a means for normally holding the said stoppers inthe mouth .of said tubular members.

2. A dropping attachment for liquid containers consisting of two tubularmembers mounted in a closure for the mouth of said container, saidtubular members forming means for thedispensing of the liquid in thecontainer, closures forthe outer ends of said: tubular, members, a leverpivotally mounted upon 'said container closure and connected with saidtube closures and means connected with said lever to hold this levernormally in a relation that the tube closures are in their operativeposition.
